Human life is a combination of the concrete and the abstract. Our body is concrete and our mind is abstract. Both positive and negative thoughts emanate from the same brain. We know very little about ourselves. Being better aware of our own mind helps us to understand life better.
If you are committed to doing something to uplift life around you, if you are committed to compassion, to creativity, then the world will be a wonderful place. More often than not, we are stuck in our own mindsets.
